    Respirator Inspection Before each use:

    Make sure you have

    the right respirator

    for the job

    Inspect it for wearand damage.

    5/34

    Inspection Points Check for worn or

    frayed Straps &

    Hoses.Look for wear or

    damage on the seal

    of the facepiece.

    Also CheckBe sure all the screws

    are tight.

    Check rubber and

    plastic parts forflexibility.

  • 7/29/2019 Respirator requirements

    And Check Valves should be clean and seated

    perfectly.

    Check for cracks or deformities in theface shield.

    Check condition of filters, cartridges orcanisters.

    Damage to speaking diaphragm, if there isone.

    Correct Filters & Canisters Ensure you have the correct Filters &

    Cartridges for the job

    NOTE: Color codes on cartridges & filters areonly a guide. Read the label to be sure youhave the right kind. If a combination of

    elements is required check to ensure you havethe right combination on each side of therespirator.

    Full Face Respirators Check the face

    shield for clear

    view

    No cracks, gaps

    or distortions.

    Air Supplied Respirators Check

    air supply pressure

    low pressure alarms

    regulator by-pass

    hoses for damage or

    wear hose connections

    Respirator Fit Check Conduct prior to each use.

    For a respirator to work properly it must sealtightly to the face.

    Before entering an area or conducting work thatrequires a respirator, conduct a fit check to ensure

    it will keep out the air contaminants.

  • 7/29/2019 Respirator requirements

    13/34

    Positive Pressure Check Close off the exhalation valve and exhale

    gently into the facepiece.

    The face fit is considered satisfactory if a

    slight positive pressure can be built upinside the facepiece without any evidenceof outward leakage of air at the seal.

    For most respirators, this method of leaktesting requires the wearer to first removethe exhalation valve cover before closingoff the exhalation valve, and then carefully

    replacing it after the test.

  • 7/29/2019 Respirator requirements

    14/34

    Negative Pressure Check Close off the inlet opening of the

    canister or cartridge(s) by covering it

    with the palm of the hand(s) or byreplacing the filter seal(s).

    Inhale gently so that the facepiececollapses slightly, and hold your breathfor ten seconds.

  • 7/29/2019 Respirator requirements

    15/34

    Safety Note: The design of some cartridges may require the

    test be performed by covering the inlet opening

    of the cartridge with a thin latex or nitrile gloveto effectively seal the inlet.

    If the facepiece remains in its slightly collapsed

    condition, and no inward leakage of air is

    detected, the tightness of the respirator is

    considered satisfactory.

    Manufacturer's Procedures The respirator manufacturer's

    recommended procedures for performing

    a user seal check may be used instead ofthe positive and/or negative pressurecheck procedures, provided that they areequally effective in detecting seal leakage

    compared to the positive pressure andnegative pressure checks previouslydescribed.

    Respirator Cleaning Remove and clean filters, cartridges, valve

    assemblies and any other detachable parts.

    As you clean and dry each part of the

    respirator, inspect carefully to be sure it is

    in good condition.

  • 7/29/2019 Respirator requirements

    19/34

    Basic Procedure Make sure flexible parts

    are still flexible, and

    check the stretch ofelastic bands.

    Generally, a mild

    detergent and a soft

    brush are used for

    cleaning.

  • 7/29/2019 Respirator requirements

    20/34

    Rinse the respirator Thoroughly in clean, warm water. Rinsingis extremely important because a residue of

    the cleaning agent can damage the

    respirator and irritate skin.

    Be sure all parts are thoroughly dry before

    putting the respirator back together again.

    Use a soft, lint-free cloth to absorb most of

    the water and a fan to speed up the drying

    process.

    21/34

    Disassemble Respirator Remove filters, cartridges, or canisters.

    Disassemble facepieces by removingspeaking diaphragms, demand orpressure-demand valve assemblies, hoses,or any components recommended by the

    manufacturer.

    Discard or repair/replace any defectiveparts.

  • 7/29/2019 Respirator requirements

    22/34

    Wash All Parts Wash components in warm

    (43C/110F maximum) water with a

    mild detergent or with a cleanerrecommended by the manufacturer.

    A soft bristle (not wire) brush may beused to facilitate the removal of dirt.

  • 7/29/2019 Respirator requirements

    23/34

    Rinse All Parts After Washing Rinse components thoroughly in clean,

    warm (43C/110F maximum),

    preferably running, water.

    Drain the parts to remove excess water.

  • 7/29/2019 Respirator requirements

    24/34

    Disinfect All Parts When the cleaner used does not contain a

    disinfecting agent, respirator components

    should be immersed for two minutes inHypochlorite solution (50 ppm of

    chlorine) made by adding approximately

    one milliliter of laundry bleach to oneliter of water at 43C/110F

  • 7/29/2019 Respirator requirements

    25/34

    Or Use Liquid solution of iodine (50 ppm iodine)

    made by adding approximately 0.8

    milliliters of tincture of iodine (6-8 gramsammonium and/or potassium iodine/100

    cc of 45% alcohol) to one liter of water at

    43C/110F

  • 7/29/2019 Respirator requirements

    26/34

    Also acceptable are Other commercially available

    cleansers of equivalent

    disinfectant quality when used asdirected, if their use is

    recommended or approved by the

    respirator manufacturer.

  • 7/29/2019 Respirator requirements

    27/34

    Rinse All Parts After Disinfecting Rinse components thoroughly in

    clean, warm (43C/110F

    maximum), preferably running,water.

  • 7/29/2019 Respirator requirements

    28/34

    Drain the parts The importance of thorough

    rinsing cannot be

    overemphasized. Detergentsor disinfectants that dry on

    facepieces may result in

    dermatitis.

  • 7/29/2019 Respirator requirements

    29/34

    Disinfectant Note In addition, some disinfectants

    may cause deterioration of

    rubber or corrosion of metalparts if not completely

    removed.

    30/34

    Reassemble & Test After Drying Reassemble facepiece,

    replacing filters, cartridges, and

    canisters where necessary.

    Test the respirator to ensure that

    all components work properly.

    Respirator Storage When storing a respirator, even

    overnight.

    Flex the rubber parts to make sure

    they are not twisted or bent.

    Seal the respirator in a plastic bag.
